About the'lling 'tubellliisflal corkv'24 ff-Whichzmay relzila'ee' the'fordinarylieorkf f-z the bottle toibe 2 emptied.

`A tube '25 having-at its end'the metering plug 2 8 extends through theilling tube M and through the orii'lcef I8 of cap i6, being sealed with the said cap i6. f-Atopcasing is Vpress iitted in sealed relationshipover the bottom casing l' and is orifloed Iat 32, carrying in sealed relationship through the said orice'the spout 3&2. The top casing'30 is'also oriiice'dat 3b and carries in sealed relationship therethrough-the breather tube 38. The spout34 extends into a siphon cupll which is oriced at 42-to'receive the tube 2t and which hasabaie plate'flangellil-adjacent the extremity 46 of the breather tube 38.

vMy dispenser Amay be 'constructed in any suitable-common mannnerg'but brass tubing and brass sheet-stock -arepreferre'd with the exception of the cork'24 vwhich may-be of suitably resistant rubber. All metal parts may be soldered together for support, Aand thus the spout 34 and breather tube38 are carried-by the top casing 30 While the siphon cup '40 is carriedfby the tube 26 and the jcapv I, the tube 26 receiving its support from the filling tube [4 Vand the cap I6.

Vbottle' permits fluid therein to pass through the iilling tube M'and out the orifice 22 into the dis penser proper.

The filling of the dispenser properv continues until thefluid vlevel reaches the Ainneredge 43 of the spout34, vvhen' siphoning commences. At this "point, airis cutfofrirom' the tube 2t and thence 'the bottle, andffluid'no longer issues from the orice22. "Thebreather tube 38` permits van atmospheric'- pressuretobe maintained with the dispenserr for siphoning` purposes, and the Yiiange plate Mover' the breather tube extremity 155 pre- =vents any spilling of "fluid through the said breather tube during the dispenser lling operation.

Siphoning 'of' the fiuidfinV the dispenser conslif-ofithe cup FM. lWhen thefluid level has commencing `anotherxeycle Y2'hel'time' interval between pouring cycles conlsistsfloftl'ie timelnecessaryfforairto enter the bottle through the tube 26 and permit fluid to fill the dispenseroto alevelwitli the inside edge @8 of the `vs'po'utiil.- NormallyV some fluid enters the tube 26 during the operating cycle by virtue of the inertia of the fluid entering the'dispenser in the usual manner and as a result of reduction of pressure in the tube 26 during siphoning. This fluid does not immediately drain out, and when the Siphon is broken and air again starts through the tube 26, the remaining fluid presents an obstacle through which the air must flow. The entering air also tends to hold the fluid in the tube 2S and in fact pushes some of it out of the tube 26 and back into the bottle, i obstacle lengthens the time needed for enough air topass into the bottle to fill the head.

For lessening the time interval between pour- 4 said casing interposed between said lling tube and said Venting means.

3. A device of the class described comprising: a casing adapted to coact with a container; a spout venting said casing; a Siphon cup within said casing and about said spout; a tube venting said Siphon .cup and extending into said container; a second tube within said rst tube Venting said siphon cup; a filling tube projecting from said casing and extending into said con-V tainer; means for venting said casing independ- AVVent of said spout and said filling tube; and a baf- V fle Within said casing extending from said Siphon This fluid,

ing cycles, I have provided, as shown in Fig. 4,1

an inner tube 52 within the tube 26. The inner tube 52 is so disposed and iixed within the tube 26 that during the pouring operation it is against the top of the inner periphery of the said tube 26 and its innermost' end is spacedY from the metering'plug 28. The fluid that enters the tube 26,' through the plug 28, enters the tube proper -but does not enter the inner tube 52, it vclings to the walls of the tube 26 and flows into the space between tubes 2% and 52; thus during the di"- penser refilling operation, -air passing into the bottle by-passes the fluid obstacle between the tubesV 2B and 52 by flowing through the tube 52.

I have found that in one embodiment of my invention, wherein was used Simply the tube 25, the interval between pouring cycles was three seconds, whereas, with the inner tube 52-placed within the tube-2S in the samevstructure, the time interval was but one second. Thus, my dispenser might be constructed withoutV the inner tube 52 Yforohome use, for instance, wherein a relatively substantial time interval is desired between pouring cycles; and it might be constructed with the said inner tube 52 for commercial use, as in Vpublicopurveying places where it is desired that thepouring cycles occur more frequently.

- ,Since siphoning inV my dispenser takes place only while the fluid level is between the inner edge'll of the'spout 313 and the edge 5) of the `cup 4B, it is'apparent that thecapacity of my dispensermay be varied by varying the distance 1. A device of the class described comprising:
